Multiply 2-Digit by 1-Digit (Step-by-Step)

KS2 MATHS

Multiply a 2-digit number by a 1-digit number using splitting: tens + ones, two products, then add.

10 questions - untimed quiz

KS2 ARITHMETIC PRACTICE

Multiply 2-digit by 1-digit (step-by-step)

This page guides children through splitting a 2-digit number into tens and ones, multiplying each part, then adding the two products. Each step unlocks only when the previous one is correct.

WHO THIS IS FOR

Best for children aged 7-11 (Years 3-6) who know their times tables fairly well and want a clear written-method alternative to long multiplication.

WHAT YOU LEARN

Split the number into tens + ones (e.g. 87 = 80 + 7)
Multiply each part by the 1-digit number
Add the two products to get the final answer
Catch mistakes early and correct them before moving on

A GOOD PRACTICE ROUTINE

Start untimed and say the steps out loud (split, multiply, add)
If you get stuck, rewrite the split using tens and ones
Do 8-12 questions per session, 4-5 days per week
When it feels easy, switch to timed for 5 minutes to build fluency

COMMON MISTAKES TO WATCH

Splitting incorrectly (tens must be a multiple of 10)
Forgetting to multiply the tens part (e.g. 80×6)
Mixing up the two partial products
Addition slip at the final step
